public List<Expression<Boolean>> getExpressions()

Implements javax.persistence.criteria.Predicate.getExpressions.

Doc from javax.persistence.criteria.Predicate.getExpressions.

Return the top-level conjuncts or disjuncts of the predicate. Returns empty list if there are no top-level conjuncts or disjuncts of the predicate. Modifications to the list do not affect the query.

Returns:List<Expression<Boolean>>

list of boolean expressions forming the predicate

public Predicate.BooleanOperator getOperator()

Implements javax.persistence.criteria.Predicate.getOperator.

Doc from javax.persistence.criteria.Predicate.getOperator.

Return the boolean operator for the predicate. If the predicate is simple, this is AND.

Returns:Predicate.BooleanOperator

boolean operator for the predicate

Implements org.hibernate.query.criteria.internal.predicate.PredicateImplementor.isJunction.

Doc from org.hibernate.query.criteria.internal.predicate.PredicateImplementor.isJunction.

Is this a conjunction or disjunction?

Returns:boolean

true if this predicate is a junction (AND/OR); false otherwise

Doc from javax.persistence.criteria.Predicate.isNegated.

Whether the predicate has been created from another predicate by applying the Predicate.not() method or the CriteriaBuilder.not() method.

Returns:boolean

boolean indicating if the predicate is a negated predicate

public void registerParameters(ParameterRegistry registry)

Parameters
registry:ParameterRegistry

The parameter registry with which to register.

public String render(boolean isNegated, RenderingContext renderingContext)

Implements org.hibernate.query.criteria.internal.predicate.PredicateImplementor.render.

Doc from org.hibernate.query.criteria.internal.predicate.PredicateImplementor.render.

Form of Renderable#render used when the predicate is wrapped in a negated wrapper. Allows passing down the negation flag.

Note that this form is no-op in compound (junction) predicates. The reason being that compound predicates are more complex and the negation is applied during its creation.

Parameters
isNegated:boolean

Should the predicate be negated.

renderingContext:RenderingContext

The context for rendering

Returns:String

The rendered predicate fragment.
